Patent License Agreement - F. Hoffman-La Roche Ltd., Roche Molecular Systems Inc. and Invitrogen Corp.
PATENT LICENSE AGREEMENT This is a patent license agreement ("Agreement"), and effective as of July 1, 1998. by and among F. Hoffmann-La Roche Ltd, a Swiss corporation with offices at Grenzacherstrasse 124, CH-4070 Basel, Switzerland and Roche Molecular Systems, Inc., a Delaware corporation having an office at 1080 U.S. Highway 202, Branchburg Township, Somerville, New Jersey 08876-1760 (BOTH OF WHICH ARE REFERRED TO HEREIN AS "ROCHE"), and Invitrogen Corporation, a Delaware corporation with offices at 1600 Faraday Avenue, Carlsbad, California 92008 (HEREINAFTER REFERRED TO AS "INVITROGEN") *********************** BACKGROUND A. ROCHE owns United States Patents Nos. 4,683,195, 4,683,202 and 4,965,188 and the corresponding foreign counterpart patents and patent applications, describing and claiming nucleic acid amplification processes including, INTER ALIA, a process known as the polymerase chain reaction ("PCR") process. B. ROCHE also owns certain patents and patent applications, filed worldwide, relating to purified natural, as well as recombinant, thermostable DNA polymerases, as well as compositions including said polymerases, including for example, DNA polymerases isolated from Thermus species and fragments and mutants thereof. C. ROCHE also owns United States Patent No. 5,075,216 and the corresponding foreign counterpart patents and patent applications relating to sequencing with Taq DNA polymerase. D. ROCHE also owns United States Patent Nos. 5,407,800, 5,322,770 and 5,310,652 and the corresponding foreign counterpart patents and patent applications relating, inter alia, to reverse transcription using a thermostable polymerase. E. The Perkin-Elmer Corporation ("P-E") has exclusive rights in certain fields, including the field of research, pursuant to an agreement dated December 11, 1991 with ROCHE and has Enzyme/PCR Research Products 1 v.2061097 <PAGE> certain rights to grant sublicenses in said fields. Under separate agreements between ROCHE and P-E and in consideration of a share of royalties due hereunder, P-E has released ROCHE from so much of P-E's rights in the aforementioned fields as is necessary for ROCHE to convey to INVITROGEN the rights specified in this Agreement. F. INVITROGEN wishes to obtain the right to make, use and sell to the research and to other markets products covered by AMPLIFICATION PATENT RIGHTS, POLYMERASE PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS and/or SEQUENCING PATENT RIGHTS, as hereinafter defined. G. In structuring the present Agreement, the Parties have considered the possibility that novel polymerases may be developed by INVITROGEN (and others) that are useful in, and that without a license from ROCHE, INVITROGEN may not pass on to its customers the right to use said polymerases in the PCR PROCESS, or in process covered by RT or RT-PCR PATENT RIGHTS. It is INVITROGEN's desire to promote and sell such internally developed, or licensed or purchased polymerases for use in the PCR PROCESS, or in processes covered by RT and/or RT-PCR PATENT RIGHTS and to pass on to the purchaser such a license and ROCHE is willing to permit INVITROGEN to do so. H. In addition, the parties take note that INVITROGEN may market the products licensed hereunder in conjunction with other products, components or materials, both separately or together, and in various package arrangements, which may be useful in the PCR PROCESS, and/or processes covered by RT AND RT-PCR PATENT RIGHTS. Taking this into consideration, for the mutual convenience of the parties, the products on which INVITROGEN will pay a royalty, that is the royalty base, will include those products on which INVITROGEN will pay a royalty, that is the royalty base, will include those products as specifically described below that are adapted for, promoted or supported for use with the patent rights licensed herein. Futhermore, in an effort to minimize customer confusion as to which INVITROGEN products in fact permit the customer to practice the PCR PROCESS, and/or processes covered by RT AND RT-PCR PATENT RIGHTS without additional licenses, INVITROGEN agrees, as is further described below, to give special consideration to the manner in which it promotes and sells its other products which may be useful in the PCR PROCESS and/or processes covered by RT AND RT-PCR PATENT RIGHTS but which are not specifically licensed by ROCHE for that purpose. NOW THEREFORE, for and in consideration of the mutual covenants contained herein, ROCHE and INVITROGEN ("the Parties") agree as follows: 1. DEFINITIONS For the purpose of this Agreement, and solely for that purpose, the terms set forth hereinafter shall be defined as follows: 1.1 The term "AFFILIATE" of a designated party to this Agreement shall mean: a) and organization of which fifty percent (50%) or more of the voting stock is controlled or owned directly or indirectly by either party to this Agreement; Enzyme/PCR Research Products 2 v.2061097 <PAGE> b) an organization which directly or indirectly owns or controls fifty percent (50%) or more of the voting stock of either party to this Agreement; c) an organization, the majority ownership of which is directly or indirectly common to the majority ownership of either party to this Agreement; and d) an organization under a), b), or c) above in which the amount of said ownership is less than fifty percent (50%) and that amount is the maximum amount permitted pursuant to the law governing the ownership of said organization. It is understood and agreed, however, that the term "AFFILIATE" shall not include Genentech Inc., a Delaware corporation. 1.2 "AMPLIFICATION PATENT RIGHTS" shall mean the nucleic acid amplification processes covered by United States Patent Nos. 4,683,195, 4,683,202 and 4,965,188, and those claims in foreign patents and patent applications which correspond to issued claims in the above patents and which foreign patents and patent applications claim priority from patent applications on which the above patents are based, and access to which patents and patent applications are necessary for INVITROGEN to manufacture, use and sell products which include a label license under AMPLIFICATION PATENT RIGHTS, in accordance with the rights granted in Sections 2.2 - 2.3 hereto. 1.3 "APPLICATION FIELDS" shall mean those fields listed in Appendix A. 1.4 "APPLICATIONS KIT" shall mean a LICENSED PRODUCT in combination with all such other reagents, enzymes or other materials as are necessary to perform a PCR-based assay or nucleic acid sequencing in the APPLICATION FIELD for which it is sold. 1.5 "AUTHORIZED THERMAL CYCLER" shall mean a thermal cycler or temperature cycling instrument whose use in automated performance of the PCR PROCESS in the RESEARCH FIELD and APPLICATION FIELDS is covered by the up-front fee component of a PCR PROCESS license. The up-front component of that license may be purchased from P-E. Alternatively, the up-front component of that license may be obtained through the purchase of thermal cycler(s) or temperature cycling instrument(s) bearing a valid label conveying the up-front PCR PROCESS license component. 1.6 "INVITROGEN ENZYME" shall mean any thermostable polymerase that is not a ROCHE PATENTED ENZYME, is not within POLYMERASE PATENT RIGHTS, and is developed by INVITROGEN or is purchased or licensed by INVITROGEN from a third party, which enzyme may be used in or with the PCR PROCESS and/or processes covered by RT AND RT-PCR PATENT RIGHTS. An enzyme shall not be included in this definition if INVITROGEN demonstrates to ROCHE'S satisfaction that said enzyme is in fact used predominantly for other than the PCR PROCESS and/or processes covered by RT AND RT-PCR PATENT RIGHTS. Unless excluded as provided herein, all sales of said INVITROGEN ENZYMES are assumed to be for use in the PCR Process and/or processes covered by RT AND RT-PCR PATENT RIGHTS. Enzyme/PCR Research Products 3 v.2061097 <PAGE> 1.7 "LICENSED APPLICATION PRODUCT" shall mean a) an APPLICATIONS KIT for a LICENSED APPLICATION FIELD or b) reagents, components or other materials which are sold in connection with the sale of an APPLICATIONS KIT for a LICENSED APPLICATION FIELD by INVITROGEN and which are adapted for or promoted or supported for use by customers in PCR TESTING or nucleic acid sequencing, or RT AND RT-PCR in APPLICATION FIELDS.

Notwithstanding the foregoing, it is understood and agreed that such LICENSED RESEARCH PRODUCT shall not contain, without ROCHE's specific approval, which approval shall be strictly discretionary with ROCHE, nucleic acid sequences homologous to the nucleic acid sequences of any human infectious agent or pathogen. 1.11 "NET SALES" shall mean gross invoice amount less a) discounts allowed and taken, in amounts customary in the trade, and b) sales and/or use taxes and/or duties for particular sales. No allowance or deduction shall be made for commissions or fees for collection, by whatever name known. NET SALES shall be calculated on the basis of sales or transfers to end users by INVITROGEN or an AFFILIATE or distributor. In the event INVITROGEN is unable to account for sales to third-party end users by its distributors, the NET SALES shall be calculated as the sales price to such distributors multiplied by 1.67, which factor Enzyme/PCR Research Products 4 v.2061097 <PAGE> represents a 40% margin allowed to the distributor. Sales to a third party controlling, controlled by, or under common control with INVITROGEN, or enjoying a special course of dealing with INVITROGEN, shall be determined by reference to the listed or published price for the product sold or transferred which would be applicable in an arm's length transaction, with an unrelated third party. In Japan, if INVITROGEN does not use a distributor, but instead, sales are made to end users through a WHOLESALER, and INVITROGEN is unable to account for sales to third-party end users by said WHOLESALER in Japan, the Net Sales shall be calculated as the sale price to such WHOLESALER multiplied by 1.20, which factor represents a 17% margin allowed to the WHOLESALER in Japan. INVITROGEN and ROCHE agree that ROCHE may amend this factor in the event that market conditions change such that the prevailing margin to WHOLESALERS differs from 17% by 2% or more. 1.12 "PCR PROCESS" shall mean the polymerase chain reaction (PCR) process, which is one of the amplification processes covered by AMPLIFICATION PATENT RIGHTS. 1.13 "POLYMERASE PATENT RIGHTS" shall mean a) TAQ PATENT RIGHTS; and b) those claims of those United States patents and patent applications listed in Schedule 1 hereto, and those claims in non-US patents and patent applications which claim priority from the patents and patent applications on which the patents and patent applications in Schedule 1 are based, and access to which patents and patent applications are necessary for INVITROGEN to manufacture, use and sell ROCHE PATENTED ENZYMES, other than A TAQ REAGENT, in accordance with the rights granted in Section 2.2. hereto. 1.14 "RESEARCH FIELD" shall mean the internal use by an end user of a product solely in applications of the end user (or in applications of the end user's customer, if the end user is performing contract research) in scientific research and development; and by way of example but not by way of limitation, expressly excludes: a) reportable results generated from clinical applications in humans or animals such as the detection or measurement, treatment, prevention or mitigation of disease or other health-related condition; the detection of pathogens, detection of genetic disease or genetic predisposition to disease; tissue transplantation typing; and parentage determination; b) the use of PCR to manufacture any products for sale; c) the commercial application of Taggants, which shall be defined herein to be the application of the PCR PROCESS to identify any synthetic nucleotide sequence which has been inserted, dispersed or applied into a product, substance or organism in order to identify such product, substance or organism or to convey other specific information; Enzyme/PCR Research Products 5 v.2061097 <PAGE> d) quality assurance and quality control, including without limitation, conformance with specifications, purity, batch to batch consistency whether performed internally or for third parties on a commercial basis; and e) Forensic and Human Identity Applications (as defined in Appendix A); f) Environmental Testing Applications (as defined in Appendix A); g) Agricultural Plant Applications (as defined in Appendix A); h) Animal Identity Testing and Positive Trait Breeding Applications (as defined in Appendix A); i) Food Testing Applications (as defined in Appendix A). 1.15 "ROCHE PATENTED ENZYME" shall mean a) a TAQ REAGENT; or b) an enzyme the manufacture, use or sale of which would be covered by at least one VALID CLAIM within paragraph (b) of POLYMERASE PATENT RIGHTS and which ROCHE has agreed to include in Schedule 2 hereto.

Notwithstanding the foregoing, ROCHE hereby grants to INVITROGEN the right to sublicense current INVITROGEN AFFILIATES, that is AFFILIATES of INVITROGEN Enzyme/PCR Research Products 10 v.2061097 <PAGE> on the Effective Date of this Agreement. INVITROGEN hereby accepts that right, and grants to all of its current AFFILIATES, and on their behalf accepts, sublicenses as provided herein. INVITROGEN's AFFILIATES shall not have the right to grant further sublicenses to any other AFFILIATE or third party. b) INVITROGEN shall provide prior written notice to ROCHE of AFFILIATES operating under its sublicense. Sublicenses to AFFILIATES of INVITROGEN shall accord with all requirements of this Agreement and shall include the following terms and conditions: i) That the sublicense is co-terminus with this Agreement as to term and TERRITORY, except as provided below; ii) To provide INVITROGEN with such complete and accurate information as is necessary to calculate the NET SALES of each sublicensed product sold or otherwise transferred by such AFFILIATE; iii) To grant to ROCHE the right to inspect under the terms and conditions in Section 4.4; and iv) To be bound by all terms and conditions of this Agreement, including without limitation, the indemnity provisions of Section 11. Notwithstanding the foregoing, INVITROGEN shall remain primarily responsible both for its and its sublicensed AFFILIATES' performance under this Agreement. c) Unless terminated sooner pursuant to Section 6 herein, any sublicense to an AFFILIATE shall terminate immediately without any notice or action on the part of INVITROGEN if: i) Such sublicense no longer meets the definition of an AFFILIATE set forth in Section 1.1 hereof; or ii) INVITROGEN sells its business in LICENSED PRODUCTS to another person. In the event of termination on either of the bases set forth in Section 2.6 c i) or ii) above, then all rights granted to and obligations undertaken by the sublicensee and INVITROGEN under such sublicense shall terminate immediately without any action on the part of INVITROGEN, the AFFILIATE or ROCHE, except for the rights and obligations surviving termination set forth in Sections 6.7 and 6.8 herein, and INVITROGEN shall provide written notice to ROCHE of such termination. d) No sublicensed AFFILIATE shall have the right to assign or otherwise transfer its sublicense in whole or in part to any other AFFILIATE or third party, whether by written instrument or by operation of law. An assignment of a sublicense in Enzyme/PCR Research Products 11 v.2061097 <PAGE> violation of the foregoing sentence shall include, but is not limited to, either of the following occurrences: i) The sale, directly or indirectly, to any third party of a beneficial interest in fifty percent (50%) or more of the outstanding voting securities of such AFFILIATE; or ii) The issuance or sale to any third party of a class of securities of INVITROGEN, the interest dividend or other distribution on which is measured in substantial part by the performance of such AFFILIATE such that such third party, acting alone or in concert with other third parties, become the beneficial owner of fifty percent (50%) or more of such class of INVITROGEN securities. e) Nothing herein shall prohibit INVITROGEN from distributing LICENSED PRODUCTS on behalf of any sublicensed AFFILIATE. 2.7 Except as is specifically provided herein, this Agreement shall not limit the rights of ROCHE in any way. It is specifically understood that as between the Parties to this Agreement, ROCHE reserves the right itself or through its AFFILIATES to practice under POLYMERASE PATENT RIGHTS, SEQUENCING PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS and AMPLIFICATION PATENT RIGHTS, including the PCR PROCESS itself, and to sublicense, assign or otherwise transfer such rights to others for any purpose whatsoever. 2.8 INVITROGEN shall affix to each particular LICENSED RESEARCH PRODUCT or LICENSED APPLICATIONS PRODUCT licensed hereunder, either on a product insert accompanying the product or on the product itself, one of the labels described in Appendix C, as ROCHE shall direct, or such other label as ROCHE may direct from time to time. Such changes in labeling shall be subject to the approval of INVITROGEN, which shall not be unreasonably withheld. As to the labels set forth in Appendix C, INVITROGEN understands and agrees that the notices numbered 1 through 5 reflect ROCHE's present label licensing policy and shall be used on the labels for INVITROGEN products as appropriate. In regard to any changes in labels directed by ROCHE, INVITROGEN shall have a reasonable time period over which to change its labels. 2.9 a) INVITROGEN hereby covenants that it shall sell, market and otherwise promote products licensed hereunder in accordance with the terms of this Agreement and it shall use its best efforts, as described herein, and shall contractually require all of its distributors to also use their best efforts, as described herein, to ensure that these products are sold in compliance with the letter and intent of this Agreement. To that end, INVITROGEN and its distributors shall prominently display in catalogues and brochures describing LICENSED RESEARCH PRODUCTS and/or LICENSED APPLICATION PRODUCTS, the label license statements as described in Section 2.8 and Appendix C. Furthermore, in advertisements or any other materials intended for distribution to third parties and referring in any way to Enzyme/PCR Research Products 12 v.2061097 <PAGE> products licensed hereunder and the use of said products in the PCR PROCESS, but in which it is not practical to include the complete label license statements, INVITROGEN will include a comparable restriction on use as follows: "Purchase of this product [or product name] is accompanied by a limited license to use it in the Polymerase Chain Reaction (PCR) process [and RT or other as appropriate] for ["field"] in conjunction with a thermal cycler whose use in the automated performance of the PCR process is covered by the up-front license fee, either by payment to Perkin-Elmer or as purchased, i.e., an authorized thermal cycler." or other statement approved in writing by ROCHE. b) INVITROGEN agrees that once it is notified by ROCHE or once it independently becomes aware that a particular purchaser is using or intends to use any product licensed herein in violation of AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS, or RT AND RT-PCR PATENT RIGHTS, INVITROGEN shall immediately notify said purchaser in writing that such use is unlicensed and that a license for said use must be obtained from ROCHE or P-E. INVITROGEN shall also require sublicensed AFFILIATES and distributors to report to INVITROGEN any unlicensed activities of which they become aware. INVITROGEN further agrees that continued or resumed sales by INVITROGEN, a sublicensed AFFILIATE or a distributor, to a particular purchaser of which INVITROGEN was previously notified or is otherwise aware is distributing/using any licensed product in violation of AMPLIFICATION PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS or SEQUENCING PATENT RIGHTS, shall constitute a breach of this Agreement under Section 6.5 of the Agreement. A written certification by a distributor or purchaser which is executed by an officer of said distributor or purchaser which officer may legally bind the company, that it has ceased infringing the AMPLIFICATION PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS and/or SEQUENCING PATENT RIGHTS or, alternatively, that it does not infringe said patent rights, or a written certification by INVITROGEN which is executed by an officer of INVITROGEN which officer may legally bind INVITROGEN that sales to such distributor or purchaser have ceased, shall be a cure under Section 6.5. c) Pursuant to the foregoing general requirements, INVITROGEN shall, when it receives an order for a LICENSED RESEARCH PRODUCT from any customer, which INVITROGEN recognizes as significantly exceeding that customer's typical usage requirements, contact the customer and specifically inform the customer that the AMPLIFICATION PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS and/or SEQUENCING PATENT RIGHTS conveyed to customer with the sale of such LICENSED RESEARCH PRODUCT are limited for use by the customer for internal research only and that no other rights under the AMPLIFICATION PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS and/or SEQUENCING PATENT RIGHTS outside the LICENSED FIELD are conveyed. Said customers shall be required to furnish a written certification that customer intends to use said LICENSED RESEARCH PRODUCT without violating the Enzyme/PCR Research Products 13 v.2061097 <PAGE> AMPLIFICATION PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS or the SEQUENCING PATENT RIGHTS. d) INVITROGEN agrees that it shall provide to ROCHE a copy of each of its notices to purchasers/distributors (as well as a copy of each purchaser/distributor's certification of compliance) pursuant to this Section 2.9. e) The Parties understand and hereby agree that INVITROGEN shall have no obligation to monitor or police its customers' payment of the up-front fee component of a PCR license for research or the thermal cycler "authorization" fee described in Section 1.5. INVITROGEN's obligations hereinunder in regard to AUTHORIZED THERMAL CYCLERS shall be limited to providing the label license as specified in Section 2.8 and Appendix C. However, INVITROGEN agrees not to knowingly promote, directly or through its distributors, the unlicensed use of PCR with the ROCHE PATENTED ENZYMES or INVITROGEN ENZYMES in the RESEARCH FIELD or APPLICATION FIELDS in thermal cyclers for which the up-front license fee has not been paid (not authorized). INVITROGEN and ROCHE agree that ROCHE will enforce its rights and will use its best efforts to cause P-E to enforce its rights with regard to customers of INVITROGEN using thermal cyclers that are not "authorized" in the same manner ROCHE and P-E treat their own customers in the same circumstances. 2.10 Roche hereby grants to INVITROGEN the right and INVITROGEN accepts and agrees to credit ROCHE as the source of patent rights in INVITROGEN's promotional materials, including for example advertisements, product inserts and data sheets, intended for distribution to third parties as follows: "This product is sold under licensing arrangements with F. Hoffmann-La Roche Ltd, Roche Molecular Systems, Inc. and The Perkin-Elmer Corporation." Such reference will be reasonably prominent and in materials (for example catalogues) containing multiple product descriptions, will be directly associated with information on each specific product covered by this Agreement. 2.11 In accordance with Section 2.6 b iv), sublicenses granted by INVITROGEN shall specifically require the sublicensee to comply with INVITROGEN's obligations under Sections 2.7-2.10. 3. GRANT TO ROCHE 3.1 If INVITROGEN elects to market a INVITROGEN ENZYME or elects to license third parties to make, use or sell a INVITROGEN ENZYME, ROCHE shall have an option to negotiate a nonexclusive license to manufacture and sell directly or through distributors such INVITROGEN ENZYME. INVITROGEN shall notify ROCHE of its election to market or to license third parties to market INVITROGEN Enzymes within thirty (30) Enzyme/PCR Research Products 14 v.2061097 <PAGE> days of INVITROGEN making such an election. ROCHE may exercise the said option within three (3) years after the receipt of INVITROGEN's notice. The terms of said licenses shall be negotiated in good faith by the parties, taking into consideration the relevant market factors typically considered in such agreements, but any negotiated royalty shall not exceed 10% of the Net Selling Price of ROCHE to its customers or distributors. The duration of said license shall be commensurate with the term of the last to expire of any patent covering ROCHE's customers' use of such enzyme without further payment of any kind from end user customers to INVITROGEN or its licensor, if there is one. If ROCHE does not exercise the option hereunder, ROCHE shall nonetheless be entitled to a license to make, use or sell said INVITROGEN ENZYME under the same terms and conditions as the most favorable nonexclusive license granted by INVITROGEN. 3.2 Sublicenses granted by INVITROGEN are conditioned on the sublicensee's making a grant equivalent to Section 3.1 to ROCHE. 4. ROYALTIES, RECORDS AND REPORTS 4.1 LICENSE ISSUANCE FEE For the rights and privileges granted hereunder, INVITROGEN will pay to P-E a nonrefundable, noncreditable License Issuance fee of * upon execution of the Agreement. 4.2 ROYALTIES For the rights and privileges granted under this Agreement, INVITROGEN shall pay royalties on products licensed hereunder used by INVITROGEN or its sublicensed AFFILIATES of sold, distributed, or otherwise transferred by INVITROGEN or its sublicensed AFFILIATES (with or without payment), as follows below, except as otherwise specifically modified by Section 5.2 and Appendix A: a) for a ROCHE PATENTED ENZYME or an INVITROGEN ENZYME, per Royalty Unit for each such enzyme; b) for LICENSED RESEARCH PRODUCTS and LICENSED APPLICATION PRODUCTS that include ROCHE PATENTED ENZYMES and/or INVITROGEN ENZYME, * of the Net Sales of each licensed Research Product and licensed Application Product or per Royalty Unit for each enzyme included in such Product, whichever is larger. c) for LICENSED RESEARCH PRODUCTS which contain neither ROCHE PATENTED ENZYMES nor INVITROGEN ENZYMES * Furthermore, the Parties further understand and agree that the royalty rates provided in subsections a) though c) above shall apply only for so long as Amplification Patent shall be in force. * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION." Enzyme/PCR Research Products 15 v.2061097 <PAGE> 4.3 Royalties for sales prior to the signature of the Agreement as from the first commercial sale of products licensed hereunder shall be reported together with the first report due hereunder in accordance with Section 4.5. 4.4 INVITROGEN shall keep full, true and accurate books of account containing all particulars which may be necessary for the purpose of showing the amount payable by way of royalty or by way of any other provision under this Agreement for itself and its sublicensed AFFILIATES. Such books and the supporting data shall be open at all reasonable times, for three (3) years following the end of the calendar year to which they pertain (and access shall not be denied thereafter, if reasonably available), to the inspection of an independent certified public accountant retained by ROCHE for the purpose of verifying INVITROGEN's royalty statements or INVITROGEN's compliance in other respects with this Agreement. If in dispute, such records shall be kept until the dispute is settled. The inspection of records shall be at ROCHE's sole cost unless the inspector concludes that royalties reported by INVITROGEN for the period being audited are understated by five percent (5%) or more from actual royalties, in which case the costs and expenses of such inspection shall be paid by INVITROGEN. 4.5 INVITROGEN shall within thirty (30) days after the first day of January, April, July and October of each year deliver to the addresses provided below a true and accurate royalty report. This report shall be in accordance with the royalty report form attached hereto as Appendix D. This report shall be on U.S./ex-U.S. basis and shall give such particulars of the business conducted by INVITROGEN in the United States and in territories other than the United States during the preceding three (3) calendar months as are pertinent to an accounting for royalty under this Agreement and shall include at least the following: a) separately itemized quantities of products licensed hereunder that are used, sold or otherwise transferred by INVITROGEN during those three (3) months; b) the ROYALTY UNITS of ROCHE PATENTED ENZYME(S) AND/OR INVITROGEN ENZYME(S) in each product licensed hereunder and, for each product, the calculation of ROYALTY UNITS if different from "activity units" for said enzyme as advertised, marketed or sold by INVITROGEN; c) the NET SALES of each LICENSED RESEARCH PRODUCT and LICENSED APPLICATION PRODUCT; d) the calculation of net royalties based on a royalty rate as defined in Section 4.2; e) the net royalties due. If no royalties are due, it shall be so reported. * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION." Enzyme/PCR Research Products 16 v.2061097 <PAGE> The correctness and completeness of each such report shall be attested to in writing by the responsible financial officer of INVITROGEN's organization or by INVITROGEN's external auditor or by the chairman or other head of INVITROGEN's internal audit committee. With respect to royalties due from sublicenses, attestation by INVITROGEN may be that it has obtained from sublicensed AFFILIATES attestations complying with the preceding sentence. Simultaneously with the delivery of each such royalty report, INVITROGEN shall pay to P-E the royalty and any other payments due under this Agreement for the period covered by such report. All amounts payable hereunder by INVITROGEN shall be payable in United States currency and sent by the due date, together with the royalty report, to the following address: Applied Biosystems Division The Perkin-Elmer Corporation 850 Lincoln Centre Drive Foster City, California 94404, U.S.A. Attn: Licensing Manager or to such other address as P-E may designate. A copy of the royalty report shall also be sent to: Roche Molecular Systems, Inc. 1145 Atlantic Avenue, Suite 100 Alameda, California 94501, U.S.A. Attn: Licensing Manager or to such other address as ROCHE may designate. 4.6 Royalties accruing on account of sales in countries other than the United States shall be payable in United States dollars in amounts based on the New York rate of exchange as quoted in The Wall Street Journal (WSJ) for the last business day of each quarter. If the WSJ does not publish any such rate, a comparable publication shall be agreed upon from time to time by the parties, and with respect to each country for which such rate is not published in the WSJ or in a comparable publication, the parties shall use the applicable rate for such date by the appropriate governmental agency in such country. 4.7 a) The Parties agree that the royalty rates and unit fees set forth in Section 4.2 are reasonable in view of the proprietary rights associated with the products licensed hereunder and the consequent relative importance of these products in the marketplace. The Parties also recognize, however, that a substantive change might occur in the marketplace, including, for example, a change in ROCHE's proprietary position, or in the status of technological alternatives that are non-proprietary to ROCHE, which change in the marketplace might significantly detract from the value added of the products licensed hereunder and thereby in light of the royalty schedule of Section 4.2, potentially makes INVITROGEN's marketing position correspondingly less competitive. Should such changes occur in the marketplace, the parties agree to discuss whether adjustments to the financial terms herein would be appropriate and otherwise acceptable to ROCHE. * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION." Enzyme/PCR Research Products 17 v.2061097 <PAGE> b) In an effort to assist INVITROGEN in remaining competitive in light of such changes in the marketplace, the parties have specifically agreed that the following mechanism shall be available to provide INVITROGEN royalty relief if ROCHE ascertains that P-E's worldwide combined "Average Transaction Price" ("ATP") for * in a * period (as is provided below) is less than * per unit, then INVITROGEN'S unit royalty for * for that same * period shall be * per unit multiplied by the fraction * [* per unit], but in no event shall INVITROGEN'S unit royalty be reduced below * per unit for * nor raised above * per unit. Such ATP calculations shall be made by ROCHE for the * period preceding * and INVITROGEN shall be notified * after the beginning of each such * period if it is or is not entitled to a credit for the * periods comprising such * period. By way of example as to how said royalty adjustments will operate, on each *, ROCHE shall ascertain P-E's ATP for the * period beginning * prior to said * date and shall calculate the per-unit royalty as above described. If that per unit royalty is other than * per unit, ROCHE shall so notify INVITROGEN no later than on *, respectively, of * so that INVITROGEN may take the appropriate credit against the royalties next owed. As used herein, "Average Transaction Price" shall mean the average transfer price per unit for all * transferred by P-E or its Affiliates to end users (which, in P-E's case shall mean to other than ROCHE or ROCHE's Affiliates). "Average Transaction Price" shall be calculated by dividing the worldwide aggregate Net Sales of all products transferred by P-E that contain only * by the worldwide aggregate Units of * contained in those products. ROCHE represents that it has the right and is able to obtain access to such information about P-E's Average Transaction Price (ATP) as is necessary for ROCHE to make the above (ATP) calculations accurately. Except as is specifically provided by the mechanism to provide royalty relief described in Section (b) above, ROCHE shall be under no obligation to change or renegotiate any sections, provisions or terms of this Agreement. 4.8 Withholding tax, if any, levied on any royalty and/or on any other payments to be paid hereunder, will be paid by INVITROGEN to the proper taxing authority and proof of payment will be sent to P-E. Any such withholding tax paid by INVITROGEN, will be fully credited against the royalty due to P-E. * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION." Enzyme/PCR Research Products 18 v.2061097 <PAGE> 4.9 Any amount not being paid by INVITROGEN when due will bear interest of one and a half percent (1.5%) per month from the due date until paid. 5. LICENSE IN ADDITIONAL FIELDS 5.1 INVITROGEN may elect at the time of execution of this Agreement, or shall maintain an option, exercisable for five years from the signature date of this Agreement, to add APPLICATION FIELDS to the LICENSED FIELDS. 5.2 Appendix A specifies for each field to which this election and option applies a license issuance fee, where applicable, and the applicable royalty rate if such rate is different from that specified in Section 4.2, for each such field. Roche shall have the right to change said license issuance fees and royalty rate after two years from the signature of this Agreement for any field which has not become a LICENSED FIELD pursuant to Section 5.3. 5.3 Each individual field in addition to RESEARCH FIELD will become a LICENSED FIELD when the respective election and option has been exercised and the specified license issuance fee for that field has been paid. 6. TERM AND TERMINATION 6.1 This license is granted retroactively to INVITROGEN as from the date of first commercial sale of LICENSED PRODUCTS, LICENSED RESEARCH PRODUCTS and/or LICENSED APPLICATION PRODUCTS and will expire on the expiration of the last to expire of the patents within AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS, POLYMERASE PATENT RIGHTS, RT AND RT-PCR PATENT RIGHTS to the extent a license of rights under any of the foregoing surviving Patent Rights is being exercised pursuant to Sections 2.1 - 2.5 hereto. 6.2 Notwithstanding any other Section of this Agreement, INVITROGEN may terminate this Agreement for any reason on ninety (90) days' written notice to ROCHE. If INVITROGEN elects to terminate this Agreement pursuant to this section, it shall within thirty (30) days of said notice to ROCHE, also notify each of its customers that INVITROGEN is no longer licensed under AMPLIFICATION PATENT RIGHTS, POLYMERASE PATENT RIGHTS, SEQUENCING PATENT RIGHTS or RT AND RT-PCR PATENT RIGHTS. 6.3 Notwithstanding any other section of this Agreement, ROCHE may terminate this Agreement, effective immediately upon notice of termination to INVITROGEN, in the event that a third party which is licensed by ROCHE to manufacture products for use in PCR-based human diagnostic testing acquires any interest, including but not limited to an ownership interest, directly or indirectly, in INVITROGEN of 50% or more. 6.4 The license granted hereunder to INVITROGEN and all sublicenses granted by INVITROGEN to its AFFILIATES shall automatically terminate upon i) an adjudication of INVITROGEN as bankrupt or insolvent, or INVITROGEN's admission in writing of its Enzyme/PCR Research Products 19 v.2061097 <PAGE> inability to pay its obligations as they mature; or ii) an assignment by INVITROGEN for the benefit of creditors; or iii) INVITROGEN's applying for or consenting to the appointment of a receiver, trustee or similar officer for any substantial part of its property or such receiver, trustee or similar officer's appointment without the application or consent of INVITROGEN, if such appointment shall continue undischarged for a period of ninety (90) days; or iv) INVITROGEN's instituting (by petition, application, answer, consent or otherwise) any bankruptcy, insolvency arrangement, or similar proceeding relating to INVITROGEN under the laws of any jurisdiction; or v) the institution of any such proceeding (by petition, application or otherwise) against INVITROGEN, if such proceeding shall remain undismissed for a period of ninety (90) days or the issuance or levy of any judgment, writ, warrant of attachment or execution or similar process against a substantial part of the property of INVITROGEN, if such judgment, writ, or similar process shall not be released, vacated or fully bonded within ninety (90) days after its issue or levy. 6.5 Upon any breach or default of a material term under this Agreement by INVITROGEN or an AFFILIATE sublicensed by INVITROGEN, this Agreement may be terminated upon ninety (90) days, written notice to INVITROGEN. Said notice shall become effective at the end of the ninety-day period, unless during said period INVITROGEN fully cures such breach or default and notifies ROCHE of such cure. Such 90-day cure period shall not apply to any uncontested royalty payments due, which uncontested payments must be made in accordance with the terms of this Agreement. 6.6 Upon termination of this Agreement as provided herein, INVITROGEN shall immediately stop selling products licensed hereunder and all rights and licenses granted to INVITROGEN by ROCHE hereunder and all sublicenses granted by INVITROGEN shall automatically revert to or be retained by ROCHE. 6.7 INVITROGEN's obligations to report to ROCHE and to pay royalties as to the sale of products licensed and sublicensed hereunder pursuant to the Agreement prior to termination or expiration of the Agreement shall survive such termination or expiration. 6.8 Upon termination of this Agreement for any reason, INVITROGEN shall destroy its inventory of all products licensed hereunder and confirm such destruction in writing within ten days of the termination of the Agreement. 7. ENFORCEMENT OF PATENTS 7.1 INVITROGEN shall advise ROCHE promptly, and shall furnish documentary proof which is reasonably acceptable to ROCHE, upon its becoming aware of substantial infringement by a third party or parties of an enforceable patent right (1) within POLYMERASE PATENT RIGHTS by the sale of "Significant Quantities" of unlicensed stand-alone enzymes in any country in the TERRITORY, or (2) within AMPLIFICATION PATENT RIGHTS by the sale of "Significant Quantities" of enzymes not within POLYMERASE PATENT RIGHTS but which enzymes are actively promoted by said third party or parties or their AFFILIATES or distributors for use in AMPLIFICATION PATENT RIGHTS in any country in Enzyme/PCR Research Products 20 v.2061097 <PAGE> the TERRITORY. Upon receipt of said written information, ROCHE agrees it shall, within its reasonable business judgment, take such action as is required to restrain such infringement. ROCHE shall be in full compliance with its obligations under this Section 7.1 if, within six (6) months of ROCHE having received said written information from INVITROGEN about any one infringing party in a particular country, (1) ROCHE notifies each third party identified by such acceptable documentary proof of ROCHE's enforceable proprietary position in the country where infringement is occurring and receives from such third parties written assurances, which shall be executed by an officer of each said third party capable of legally binding that party, that it is not infringing ROCHE's rights, or (2) said infringement has stopped, or (3) ROCHE has entered into good faith license negotiations with such third parties, or (4) ROCHE has instituted or is prosecuting an action for patent infringement against at least one infringing third party seller which is active in said country. The above six-month period may be extended with the consent of INVITROGEN. It is agreed and understood that nothing in this Section 7.1 or this Agreement shall require ROCHE to sue more than one party at a time or to sue in more than one country at any one time. For the purposes of the foregoing clauses, "Significant Quantities" of unlicensed stand-alone enzymes shall mean (1) in the case of a single third-party infringer in a particular country, at least 20%, or (2) in the case of more than one third party seller in a particular country, at least 40%, of total ROYALTY UNIT turnover, respectively, of all stand-alone enzyme(s) within POLYMERASE PATENT RIGHTS or thermostable enzymes not within POLYMERASE PATENT RIGHTS but which are "Actively Promoted" for use in AMPLIFICATION PATENT RIGHTS, in each country. For purposes of this Section 7.1, both Parties must agree as to the accuracy of said 20% or 40% figures before ROCHE is obligated under this Section 7.1 to pursue any remedial course of action vis a vis any third party with respect to sales of unlicensed stand-alone enzymes. Also, for purposes of this particular paragraph, "Actively Promoted" shall mean advertised or technically supported for use in AMPLIFICATION PATENT RIGHTS. If ROCHE is provided with the documentary proof of ongoing infringing sales as above described and ROCHE does not within the six-month period pursue one of the above options, INVITROGEN shall have the right at the expiration of the six-month period, or such other period as the parties have agreed, to reduce its royalty rate for royalties owed on stand-alone ROCHE PATENTED ENZYMES and/or stand-alone INVITROGEN ENZYMES in said country by 20%. It is understood and agreed that any royalty reduction afforded INVITROGEN pursuant to this Section 7 applies only to sold as stand-alone enzymes and not to kits containing said enzymes. INVITROGEN's right to reduce its royalties shall terminate and INVITROGEN shall resume paying full royalties in each country, as of the time (1) all such parties in such country have either delivered the written assurances described above or engaged in good Enzyme/PCR Research Products 21 v.2061097 <PAGE> faith license negotiations with ROCHE, provided that if said negotiations do not conclude within one year, INVITROGEN may again abate its royalty by 20% in the manner described above until the conclusion of a license with said third party, or (2) the filing or prosecution of an infringement suit against at least one such party in said country, or (3) as a result of the written assurances received in accordance with the foregoing or the conclusion of any licenses or litigations or otherwise, infringement in fact ceases or is reduced to below "Significant Quantities". Notwithstanding the provisions of this Section 7.1, ROCHE and INVITROGEN understand and specifically agree that nothing in this Section shall reduce INVITROGEN's royalty for stand-alone enzymes * per Royalty Unit. 7.2 Section 7.1 shall apply to sublicensed AFFILIATES and to INVITROGEN's royalty obligations for sales of sublicensed AFFILIATES as if the sublicensed AFFILIATES were INVITROGEN. 8. CONFIDENTIALITY-PUBLICITY 8.1 To the extent that, in literature for distribution to third parties, INVITROGEN refers to ROCHE, P-E or the terms of this Agreement, solely by specific inclusion of the clause provided in Section 2.10, ROCHE hereby approves of such usage and no further ROCHE review or approval shall be required for distribution of said literature. If INVITROGEN varies from the agreed-to clause in Section 2.10, then INVITROGEN agrees to obtain ROCHE's written approval prior to distributing any written information including said modified reference to ROCHE, P-E or the terms of this Agreement. ROCHE's approval shall not be unreasonably withheld or delayed and, in any event, its decision shall be rendered within three (3) weeks of receipt of the written information. Once approved, such materials, or abstracts of such materials, which do not materially alter the context of the material originally approved may be reprinted during the term of the Agreement without further approval by ROCHE unless ROCHE has notified INVITROGEN in writing of its decision to withdraw permission for such use. Sublicenses are conditioned on the sublicensed AFFILIATES' specific agreement to be bound by INVITROGEN's obligations under this Section. 8.2 Each party agrees that any financial, legal or business information or any technical information disclosed to it (the "Receiving Party") by the other (the "Disclosing Party") and identified in writing as confidential in connection with this Agreement shall be considered confidential and proprietary and the Receiving Party shall not disclose same to any third party and shall hold it in confidence for a period of five (5) years following termination of this Agreement and will not use it other than as permitted under this Agreement provided, however, that any information, know-how or data which is orally disclosed to the Receiving Party shall not be considered confidential and proprietary unless such oral disclosure is reduced to writing and marked confidential and given to the Receiving Party in written form within thirty (30) days after oral disclosure thereof. Such confidential and proprietary information shall include, without limitation, marketing and sales information, commercialization plans and strategies, research and * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION." Enzyme/PCR Research Products 22 v.2061097 <PAGE> development work plans, and technical information such as patent applications, inventions, trade secrets, systems, methods, apparatus, designs, tangible material, organisms and products and derivatives thereof. Notwithstanding the above, ROCHE shall have the right to share royalty reports with P-E. 8.3 The above obligations of confidentiality shall not be applicable to the extent that: a) such information is general public knowledge or, after disclosure hereunder, becomes general or public knowledge through no fault of the Receiving Party; or b) such information can be shown by the Receiving Party by its written records to have been in its possession prior to receipt thereof hereunder; or c) such information is received by the Receiving Party from any third party for use or disclosure by the Receiving Party without any obligation to the Disclosing Party provided, however, that information received by the Receiving Party from any third party funded by the Disclosing Party (e.g. consultants, subcontractors, etc.) shall not be released from confidentiality under this exception; or d) the disclosure of such information is required or desirable to comply with or fulfill governmental requirements, submissions to governmental bodies, or the securing of regulatory approvals. 8.4 Each party shall, to the extent reasonably practicable, maintain the confidentiality of the provisions of this Agreement and shall refrain from making any public announcement or disclosure of this Agreement or its terms without the prior consent of the other party, which consent shall not be unreasonably withheld, except to the extent a party concludes in good faith that such disclosure is required under applicable law or regulations, in which case the other party shall be notified in advance. 9. ASSIGNMENT/TRANSFERABILITY 9.1 The rights and licenses granted by ROCHE to INVITROGEN in this Agreement are personal to INVITROGEN and may not be assigned or otherwise transferred, including without limitation any purported assignment or transfer that would arise from a sale or transfer of INVITROGEN's business (or any portion of said business). Any attempted assignment or transfer shall be void and shall automatically terminate all rights of INVITROGEN under this Agreement. 9.2 ROCHE may assign all or any part of its rights and obligations under this Agreement at any time without the consent of INVITROGEN. INVITROGEN agrees to execute such further acknowledgments or other instruments as ROCHE may reasonably request in connection with such assignment. Enzyme/PCR Research Products 23 v.2061097 <PAGE> 10. NEGATION OF WARRANTIES AND INDEMNITY 10.1 Nothing in this Agreement shall be construed as: a) a warranty or representation by ROCHE as to the validity or scope of any patent included within POLYMERASE PATENT RIGHTS, AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS or RT AND RT-PCR PATENT RIGHTS; b) a warranty or representation that the practice of POLYMERASE PATENT RIGHTS, AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS or RT AND RT-PCR PATENT RIGHTS is or will be free from infringement of patents of third parties; c) an obligation to bring or prosecute actions or suits against third parties for infringement, provided, however, that this clause shall not alter INVITROGEN's rights and ROCHE's obligations under Section 7.1; d) except as expressly set forth herein, conferring the right to use in advertising, publicity or otherwise any trademark, trade name, or names, or any contraction, abbreviation, simulation or adaptation thereof, of ROCHE or P-E; e) conferring by implication, estoppel or otherwise any licenses, immunities or rights under any patents or patent applications of ROCHE other than those specified in POLYMERASE PATENT RIGHTS, AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS or RT AND RT-PCR PATENT RIGHTS, regardless of whether such other patents or patent applications are dominant or subordinate to those in POLYMERASE PATENT RIGHTS, AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS or RT AND RT-PCR PATENT RIGHTS, or under any thermal cycler or other instrument patent, or to perform PCR in the thermal cycler that is not an AUTHORIZED THERMAL CYCLER, or to make or sell any thermal cycler or other instrument for the automated performance of the PCR PROCESS; f) an obligation to furnish any know-how not provided in POLYMERASE PATENT RIGHTS, AMPLIFICATION PATENT RIGHTS, SEQUENCING PATENT RIGHTS and RT AND RT-PCR PATENT RIGHTS; or g) creating any agency, partnership, joint venture or similar relationship between ROCHE and/or P-E on the one hand, and INVITROGEN on the other hand. 10.2 ROCHE MAKES NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 10.3 Notwithstanding the foregoing, ROCHE warrants and represents that it has the right to grant the licenses provided in Sections 2 and 5. 10.4 The provisions of Section 10.1 and 10.2 regarding warranties and representations by ROCHE shall be specifically included in any sublicense granted by INVITROGEN. Enzyme/PCR Research Products 24 v.2061097 <PAGE> 11. INDEMNITY INVITROGEN shall assume full responsibility for its use of POLYMERASE PATENT RIGHTS and for its sale of ROCHE PATENTED ENZYMES and INVITROGEN ENZYMES and shall defend, indemnify and hold ROCHE and P-E and their respective officers, directors, agents, employees and stockholders, harmless from and against all liability, demands, damages, expenses (including attorneys' and expert witness fees and expenses) and losses for death, personal injury, illness or property damage, or any other injury or damage arising out of the use by INVITROGEN of the POLYMERASE PATENT RIGHTS or the preparation, use or sale of LICENSED PRODUCTS, including but not limited to, use or reliance upon such LICENSED PRODUCTS by customers of INVITROGEN. 12. * 13. GENERAL 13.1 This Agreement constitutes the entire agreement between INVITROGEN and ROCHE as to the subject matter hereof, and all prior negotiations, representations, agreements and understandings are merged into, extinguished by and completely expressed by it.

Enzyme/PCR Research Products 31 v.2061097 <PAGE> APPENDIX B ASSAY TO DETERMINE UNITS OF ENZYME 1. Taq DNA polymerase Taq DNA polymerase manufactured by INVITROGEN ("INVITROGEN-Taq") shall be assayed under the following conditions, in parallel with an assay of Roche Molecular Systems' AmpliTaq-Registered Trademark- DNA polymerase (P-E catalogue numbers N-801-0060, N-801-1012). The activity of INVITROGEN-Taq and AmpliTaq thus measured by INVITROGEN shall be normalized to the concentration stated by RMS for the AmpliTaq. Unit Definition: One unit of enzyme is defined as the amount that will incorporate 10nmoles of dNTPs into acid insoluble material per 30 minutes at 74 deg. C under the analysis conditions below. Analysis conditions: 25mM TAPS (tris-(hydroxymethyl)-methyl-amino- propane-sulfonic acid, sodium salt) pH 9.3 (at 25 deg. C); 50mM KCl; 2mM MgCl(2); 1mM Beta-mercaptoethanol; 200muM each dATP, dGTP, dTTP; 100muM [infinity - (32)P]-dCTP (0.05 to 0.1 Ci/mmole); activated salmon sperm DNA, mixed in a final volume of 50mul and incubated at 74 deg. C for 10 minutes. The salmon sperm DNA is activated by a modification of the methods in reference 1. The assay mixture (without enzyme) is prepared fresh daily and 45mul aliquots (0 deg. C) are mixed with 5mul of Taq DNA polymerase diluted in 25mM Tris-HCl pH 8, 50mM KCl, 100mug/ml autoclaved gelatin, 1mM Beta-mercaptoethanol, 0.5% (w/v) NP40 and 0.5% (w/v) Tween20. Reactions are initiated with addition of enzyme and placed at 74 deg. C. Reactions are quenched after 10 minutes with the addition of 10mul of 60mM EDTA and placed at 0 deg. C. Aliquots (50mul) are diluted with 1ml of 2mM EDTA containing 50mug/ml sheared salmon sperm DNA, and precipitated by the addition of 1 ml 20% (w/v) trichloroacetic acid and 2% (w/v) sodium pyrophosphate, and incubated at 0 deg. C for 15 min. Precipitated DNA is collected on GF/C filter discs (2.4 cm) and washed extensively with 5% trichloroacetic acid and 2% sodium pyrophosphate (7 x 5 ml), then 95% ethanol (5ml), dried and counted. ------------------------ (1) Richardson, C.C. 1966. DNA Polymerase from Escherichi coli. in PROCEDURES IN NUCLEIC ACID RESEARCH eds. Cantoni G.L. and Davies, D.R. Harper & Row, New York. p. 264. Enzyme/PCR Research Products 32 v.2061097 <PAGE> Activity concentration is determined from replicate assays (at least 3) of replicate parallel, serial dilutions (at least 3) that yield 20-90 pMoles dCMP incorporation in the assay. Activated salmon sperm DNA is used at a concentration that provides linear incorporation values with 20-100 mU of enzyme. This DNA concentration usually represents 12.5-20mug/assay. II. INVITROGEN ENZYMES AND ROCHE PATENTED ENZYMES OTHER THAN TAQ DNA POLYMERASE INVITROGEN ENZYMES shall be assayed in reference to AmpliTaq DNA polymerase (or another enzyme manufactured by ROCHE which is more comparable to the particular INVITROGEN ENZYME) in a manner similar to that described above. The analysis conditions shall be adapted to reflect the optimal activity conditions for each such INVITROGEN ENZYME. Further, the effectiveness of such enzyme in producing amplified DNA in the PCR PROCESS shall be determined in comparison with AmpliTaq DNA polymerase under the optimal conditions for each enzyme. This determination shall be performed as follows: TEMPLATE: Bacteriophage Lambda DNA TARGET: The 500 basepair fragment of bacteriophage lambda DNA extending from nucleotides 7131 to 7630 will be the target for amplification. Note: The template and primers are available in the GeneAmp-Registered Trademark- Lambda Control Reagents (Part No. N808-0008) from Perkin-Elmer. PRIMERS: 5'-GATGAGTTCGTGTCCGTACAACTGG-3' (complement of - strand: Nucleotides 7131-7155) 5'-GGTTATCGAAATCAGCCACAGCGCC-3' (complement of + strand: Nucleotides 7606-7630) CONDITIONS: 200muM each dATP, dCTP, dGTP, dTTP, 1ng/100mul. template, 1muM each primer. For AmpliTaq DNA polymerase other components are: 10mM Tris-HCl pH8.3, 1.5mM MgCl(2) and 50mM KCl. For INVITROGEN Enzyme, buffer pH and concentration, and MgCl(2) and KCl concentrations should be optimized for the INVITROGEN enzyme. Enzyme/PCR Research Products 33 v.2061097 <PAGE> The PCR should be carried out for 25 cycles. From the comparative yield of specific 500 basepair fragment, a "PCR Effectiveness Ratio" will be derived to be used in determining the ROYALTY UNIT as specified in Section 1.16. The Parties agree that calculation of such a ratio is complex and the data supporting the determination of the ratio must be reviewed and approved by ROCHE on a case by case basis. III. For purposes of calculating royalties owed on products, the concentration of enzyme (units per volume) reported must be within * of the actual activity measured by the above assays. The volume of enzyme reported to be in a product must be within +/- * of the actual measurable volume. * "CONFIDENTIAL PORTION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION."
